When does the waiting period (iddah) for a woman whose husband died on July 11, 2021, end?

The waiting period ('iddah) for a widow whose husband has passed away is four months and ten days if she is not pregnant. This is based on the Almighty's saying: "And those of you who die and leave wives behind them, they (the wives) shall wait (as regards their marriage) for four months and ten days." So, if her husband passed away on the 1st of Dhul-Hijjah, 1443 AH, her waiting period would end on the 10th of Rabi' al-Akhir, 1444 AH, corresponding to November 15, 2021 CE. However, if she is pregnant, her waiting period ends upon giving birth, based on the Almighty's saying: "And for those who are pregnant, their term is until they deliver their burdens."
